RESUMEN

Software systems usually have the same basic architectural pattern as their earlier incarnations, manifesting in decreasingly refined forms as we move back in time. Similarly, when a new problem confronts us, we try many different approaches, but over time, for the same kind of problem, solutions tend to converge to the same, more constrained, solution space.

RESUMEN

Virtually all well-structured music, music that pleases the ear and moves the spirit, is full of patterns. By comparing musical and software patterns, the author helps clarify the purposes and forms of patterns. Architectural and design patterns make software-intensive systems easier to understand and adapt to because of their regularity and simplicity.
